From: Christopher James Halse Rogers <raof@xxxxxxxxxx>
This is pretty much functional for both SNA and UXA, but can't reasonably
be applied until the Xserver patch has landed, and that needs more work.
This demonstrates the approach, however.
There's probably some code to be shared with XWayland support, around the
output handling (or lack thereof) and possibly integration with the underlying
compositor for SwapBuffers etc.
